Specification of Iietters Patent. Patented Oct, 15,1918.

Application filed July 24, 1917. Serial No. 182,571.

To all whom it may concern:

Be it known that I, ELLSWORTH GAMBLE, a citizen of the United States, residing at Waverly, in the county of Tioga and State of New York, have invented new and useful Improvements in Ether-Masks, of which the following is a specification.

This invention relates to means for administering ether, chloroform or other analogous drugs and aims to provide a mask which is adapted to contain an anesthetic and which may be secured to the patient to inclose the nose and mouth.

The primary object of the invention is to provide a self-retaining mask which includes a hollow cylindrical member formed at one end to fit the face of me patient and having secured thereto spring retaining clips for engagement with the ears of the patient, the said member being provided with an interiorly arranged retaining ring having a gauze diaphragm or wall, to form a shallow box or cup to receive the cotton or other absorbent to which the anesthetic may be applied and a gauze diaphragm or cover removably secured to the hollow cylindrical member by means of a yieldable retaining ring, the said cover forming a closure for.

the shallow box or cup.

With the above and other objects in view, the invention consists of the following novel combination and arrangement of parts, hereinafter more fully described and illus trated in-the accompanying drawings, in which Figure 1 is a plan view of a mask constructed in accordance with the present invention.

Fig. 2 is a front view of the same.

Fig. 3 is a central sectional view of the same.

Referring in detail to the drawings, the mask includes a hollow cylindrical body member 10, of sufficient diameter to include the nose and mouth of the patient, one end of the member 10 being provided with a nose receiving depression 11, so as to enable the mask to be fitted closely to the face of the patient. The end of the mask or member 10, which contacts with the face of the patient is formed with a bead 12, while the opposite end is also formed with a bead, but of a much smaller diameter as indicated at 13.

'Both ends of the cylindrical member 10 are open, the end remote from the face engaging end being provided upon the interior thereof with a ring 14, the said ring being adapted to snugly fit the inside and is provided with the wall or diaphragm 15 of gauze or other suitable material. This ring together with the gauze diaphragm forms a shallow box or cup, which is adapted to contain a cotton or other absorbent to which the anesthetic is applied.

In order to form a closure for this box or cup, the body member 10 is provided with a gauze cover or diaphragm 16, which is adapted to form a closure for the cup and is removably held in place by means of a spring ring 17, which clamps the diaphragm upon the outside of the cylinder 10, the bead 13 forming a shoulder to aid in holding the diaphragm in position.

Secured upon diametrically opposite sides of the cylinder 10 are coil springs 18, one end of these springs being secured to the cylinder as shown at 19, while the opposite ends have secured thereto wire loops 20, which are adapted to be fitted over the ears of the patient to hold the mask in position. The loops 20 are formed with an elongated portion 21, through which the ear is adapted to pass when positioning the loop and with a rounded ear engaging portion 22, which latter portion fits behind the ear to hold the loop in position.

For the purpose of adapting the mask to various types of persons, for example, children and adults. the loops 20 are adjustably secured to the mask by means of the element 19. which is provided with engaging seats 23 and 24, so that when the ends of the springs 18 are positioned within the seats 23, the ma k will be adjusted to fit the head of a child and when the said ends are positioned within the seats 24, the adiustment will accommodate an adult.

It will be seen from the foregoing that the invention provides a simple self-retaining mask adapted for the purpose of administering ether or other anesthetic, the said anesthetic being applied to an absorbent contained within the said cup 14, the diaphragm 16 providing for the removal andreplacing of the absorbent as desired.

The right is reserved to make such seats formed of Wire bent to define seats 10 located at different points along the length of the body member upon opposite sides thereof, whereby the mask may be adjusted to fit either an adult or a child.

In testimony whereof I affix my signa- 15 ture.
